Vegetables by the 50 lb. bag

I'm trying something new, getting large bags of potatoes and onions from the local Farmer's Market Basket.  For only a bout $13.50, we can buy a 50 lb. bag of potatoes, and divide them up.

Also getting onions, and hope to dehydrate them - this will be more labor intensive for me, unless some people decide to help chop onions!  And I get more dehydrators . . .to make the baggies of lentils and spices that is a meal in a bag. 

I haven't found a better source for these yet - see the post about the groups in south Florida who prepare these and basically it's a meal for about $.10. I am not buying in the bulk quantities they do but hope that we can make this work.
